Atheros Communications to Acquire Attansic Technology Company

Atheros Communications, Inc. (Nasdaq: ATHR), a leading developer of advanced wireless solutions, today announced that it has signed a definitive agreement to acquire Attansic Technology Company, a privately held Taiwan-based fabless semiconductor company specializing in Fast and Gigabit Ethernet integrated circuit solutions for PC, access point (AP) and router applications. Attansic is a majority-owned subsidiary of ASUSTek Computer Inc., the world's leading supplier of PC motherboards and manufacturer of modems and gateways through its Askey subsidiary. Attansic is headquartered in Hsinchu, Taiwan and has a large presence in Shanghai.

The addition of Attansic's Ethernet technology enables Atheros to drive towards complete, cost-efficient system solutions for Consumer and Small Office/Home Office (SOHO) wireless APs and routers. The high-value combination of Atheros' market-leading wireless LAN (WLAN) solutions, wireless network processors and Attansic's Ethernet technology represents all of the key silicon components needed in wireless APs and routers to move high speed signals from wire to air and back. By aggregating these essential technologies into a complete, single-source solution, Atheros continues on its path to deliver greater value and a greater share of the total bill of materials (BOM) of communications products.

Specifically, Gigabit Ethernet technology, when combined with Atheros' XSPAN(TM) 802.11n WLAN chipsets and recently announced AR7100 family of wireless network processors, enables optimal 802.11n AP/router performance for high quality media networking. The 802.11n WLAN standard will support up to 600 Mbps physical data rates and requires Gigabit Ethernet to achieve optimal connectivity to content and services -- from a broadband Internet connection or a local mass storage device -- to deliver a compelling whole-home media networking experience. Atheros will leverage its expertise in CMOS integration to achieve cost-efficiencies that will drive Gigabit Ethernet-enabled networking products to the mass market.

"By 2008, 100 percent of 802.11n wireless routers and access points will ship with Gigabit Ethernet ports in order to achieve the technology's full performance potential," said Craig Mathias, a principal at the wireless and mobile advisory firm Farpoint Group, located in Ashland, Mass. "Atheros is primed to take advantage of this tremendous market opportunity by offering a complete, cost-optimized networking solution to its impressive, existing SOHO customer base."

In addition, with the Attansic acquisition Atheros' world-class PC OEM customers will have access to the most cost-optimized, high-performance wireless and wired LAN technologies available today. Atheros also immediately achieves a leading position in the PC LAN-on-motherboard (LOM) market as Attansic currently supplies ASUSTek, the world's largest motherboard manufacturer, with its Gigabit Ethernet NIC and PHY products for LOM.

"With the acquisition of Attansic, Atheros gains a skilled engineering team that has strong mixed-signal design expertise and particularly strong Ethernet capability," said Craig Barratt, president and chief executive officer of Atheros. "By combining our leading wireless LAN and Ethernet technologies with Atheros' integration capabilities, we can drive the adoption of Gigabit Ethernet in the 11n router market. Additionally, we can leverage our strong customer base in the retail, PC OEM and service provider markets by offering a broader portfolio of communication technologies."

Since 1998, Atheros has developed its industry-leading position for wireless system integration in CMOS silicon. To date, Atheros has delivered eight generations of highly-integrated WLAN chipsets. Many of these products were industry firsts, including the world's first single-chip 802.11g and 802.11a/g solutions for PCI and PCI Express client devices; single-chip 802.11g solution for access points and routers; single-chip 802.11g and 802.11a/g solutions for low-power mobile and embedded devices; and its unique single-chip, triple-radio design for draft 802.11n solutions. This high level of chip integration enables Atheros' customers to build cost-effective products while maintaining excellent performance.

"We believe the combination of Atheros' and Attansic Technology's technical strengths will create the world's most competitive suite of wireless and wireline local area networking products, enabling Atheros to deliver unique value to PC OEMs and network router equipment manufacturers alike," said Jerry Shen, chairman of Attansic and president of ASUSTek AOOP Business Group.

At closing of the acquisition, Atheros expects to pay approximately $46.5 million in cash and $25 million in Atheros common stock. A portion of the cash consideration payable to the shareholders will be placed into escrow pursuant to the terms of the acquisition agreement. ASUSTek has agreed to a multi-year lockup of its stock consideration. The transaction is expected to close within three months and remains subject to regulatory requirements and other customary closing conditions. Atheros may record a one-time charge for purchased in-process research and development expenses. The amount of that charge, if any, has not yet been determined.

Attansic currently has approximately 90 employees in its Shanghai and Taiwan locations with more than 50 percent of its development force in Shanghai. The Taiwan team will be integrated into Atheros' Taiwan Development Center, created earlier this year through the acquisition of ZyDAS Corporation. The Attansic acquisition represents Atheros' continued aggressive expansion of sales and engineering resources in the Asia region to increase its presence near many of its key customers and enables the company to leverage the vast talent pool in that region.
